pip resource

Use the pip Chef InSpec audit resource to test packages that are installed using the Python PIP installer.

Availability

Install

This resource is distributed with Chef InSpec and is automatically available for use.

Version

This resource first became available in v1.0.0 of InSpec.

Syntax

A pip resource block declares a package and (optionally) a package version:

describe pip('package_name') do
  it { should be_installed }
end

where

• 'package_name' is the name of the package, such as 'Jinja2'
• be_installed tests to see if the package described above is installed

Properties

version

The version property tests if the named package version is on the system:

its('version') { should eq '1.2.3' }

Examples

The following examples show how to use this Chef InSpec audit resource.

Test if Jinja2 is installed on the system

describe pip('Jinja2') do
  it { should be_installed }
end

Test if Jinja2 2.8 is installed on the system

describe pip('Jinja2') do
  it { should be_installed }
  its('version') { should eq '2.8' }
end

Test packages installed into a non-default location (e.g. virtualenv) by passing a custom path to pip executable

describe pip('Jinja2', '/path/to/bin/pip') do
  it { should be_installed }
  its('version') { should eq '2.8' }
end
